combination and interrelation of the nervous, skeletal, and muscular systems.
Peripheral nervous system
cranial and spinal nerves that spread throughout the body and serve to relay information from bodily organs to the brain and from the brain to bodily organs.
sensory afferent neurons
Neurons that transmit nerve impulses from effector sites to the brain or spinal cord
golgi tendon organs
organs sensitive to change in tension of the muscle and the rate of that change
the neuromuscular response to sensory information
the combination and interrelation of the nervous, skeletal and muscular systems.
the functional unit of the nervous system
large group of cells that form nerves, which provide a communication network within the body
the ability of the nervous system to sense changes in either internal or external environments
neurons that transmit impulses from one neuron to another
central nervous system
consits of the brainand spinal cord and serves mainly to interpret information
the ability of the nervous system to analyze and interpret sensory information to allow for proper decision making, which produces the appropriate response.
motor (efferent) neurons
neurons that transmit nerve impulses from the brain or spinal cord to the effector sites
sensory receptors responsible for sensing distortion in bodily tissues.
receptors sensitive to pressure, acceleration and decceleration in the joint
fibers sensitive to change in length of the muscle and the rate of that change.
attach muscle to bone and provide the anchor from which the muscle can exert force and control the bone and joint.
tissue consisting of long cells that contract when stimulated to produce motion.
chemical messengers that transmit electrical impulses from the nerve to the muscle
a series of muscles that the nervous system commands to move the skeletal system.
functional unit of muscle that produces muscular contraction
the contraction fo a muscle generated by the communication between the nervous system and muscular sytesm.
bodys frame which is comprised of bones and joints
hard connective tissue that connect to create a skeletal framework
moveable places where two or more bones meet
skull, rib cage, and vertebrae column
upper and lower extremeties
flattened or indented portion of bone, which can be a muscle attachment site.
projection protruding from the bone where muscles, tendons and ligaments can attach
movements of the joings
joints that are held together by a joint capsule and ligaments and ar most associated with movement in the body.
joints that do not have a joint cavity, connective tissue, or cartilage.
connective tissue that connects bone to bone
Type I muscle fiber:
produce less force
slow to fatigue
long term contractions
Type II muscle fiber
lower in capillaries, mitochondria an myoglobin
produce more force
quick to fatigue
short term contractions
